UV‑Active Flexible Tubing

Alphacool AlphaTube HF is a PVC water‑cooling hose with a 10 mm inner diameter and 13 mm outer diameter. The UV‑Red finish glows under blacklight for a striking loop aesthetic. Supplied in a three‑metre length, it suits custom open‑loop builds. The material operates from minus ten to eighty degrees Celsius.

Build Integration

The tubing connects pump, radiator, reservoir and blocks without proprietary fittings. Its 65‑70 Shore A hardness gives enough rigidity to resist kinking on tight bends while remaining pliable for easy routing. Standard 10 mm ID compression or barbed fittings secure each joint. No adhesives or special tools are required for assembly.

Capacity And Limits

Three metres provides ample length for most mid‑tower loops with multiple components. The hose withstands a working pressure of three bar and a burst pressure of eighteen bar, giving headroom for high‑flow pumps. It is not suited for runs exceeding the supplied length or for systems demanding a larger inner diameter.

Questions about this item

How does the 10 mm inner diameter affect flow restriction during sustained high-flow operation?

The 10 mm bore keeps flow restriction low for typical D5 or DDC pumps, allowing full loop throughput without choking the pump at its rated head pressure.

Does the PVC material soften or kink when the coolant reaches the 80 °C working limit all day?

At 80 °C the tubing remains stable thanks to its 65-70 A-Shore hardness, resisting kinks and retaining shape even during continuous high-temperature circulation.

Which fittings are required to seal the 13 mm outer diameter securely?

Use 13 mm OD compression or barb fittings matched to 10 mm ID; standard G1/4 thread fittings for 13/10 mm tubing will seal the AlphaTube HF without leaks.
